Patient outcomes after implementation of transitional care protocols in elective neurosurgery: a systematic review and meta-analysis.

OBJECTIVE: 30-day readmissions are a significant burden on the healthcare system. Postoperative transitional care protocols (TCPs) for safe and efficient discharge planning are being more widely adopted to reduce readmission rates. Currently, little evidence exists to justify the utility of TCPs for improving patient outcomes in elective neurosurgery. The objective of this systematic review was to determine the extent to which TCPs reduce adverse outcomes in patients undergoing elective neurosurgical procedures. MATERIALS AND METHODS: A systematic review and meta-analysis was conducted after PROSPERO registration. Pubmed, Embase, and Cochrane review databases were searched through February 1, 2024. Keywords included: "transitional care AND neurosurgery", "Discharge planning AND neurosurgery". Articles were included if they assessed postoperative TCPs in an adult population undergoing elective neurosurgeries. Exclusion criteria were pediatric patients, implementation of Enhanced Recovery After Surgery (ERAS) protocols, or non-elective neurosurgical procedures. The primary outcome was readmission rates after implementation of TCPs. RESULTS: 16 articles were included in this review. 2 articles found that patients treated with TCPs had significantly higher chances of home discharge. 7 articles found a significant association between implementation of TCP and reduced length of stay and intensive care unit stay. 3 articles reported an increase in patient satisfaction after implementation of TCPs. 3 found that TCP led to a significant decrease in readmissions. After meta-analysis, TCPs were associated with significantly decreased readmission rates (OR: 0.68, p < 0.0001), length of stay (mean difference: -0.57, p < 0.00001), and emergency department visits (OR: 0.33, p < 0.0001). CONCLUSIONS: This systematic review and meta-analysis found that an overwhelming majority of the available literature supports the effectiveness of discharge planning on at least one measure of patient outcomes. However, the extent to which each facet of the TCP affects outcomes in elective neurosurgery remains unclear. Future efforts should be made to compare the effectiveness of different TCPs.

Twenty-three years of PCR-based seafood authentication assay development: What have we learned?

Seafood is a prime target for fraudulent activities due to the complexity of its supply chain, high demand, and difficult discrimination among species once morphological characteristics are removed. Instances of seafood fraud are expected to increase due to growing demand. This manuscript reviews the application of DNA-based methods for commercial fish authentication and identification from 2000 to 2023. It explores (1) the most common types of commercial fish used in assay development, (2) the type of method used, (3) the gene region most often targeted, (4) provides a case study of currently published assays or primer-probe pairs used for DNA amplification, for specificity, and (5) makes recommendations for ensuring standardized assay-based reporting for future studies. A total of 313 original assays for the detection and authentication of commercial fish species from 191 primary articles published over the last 23 years were examined. The most explored DNA-based method was real-time polymerase chain reaction (qPCR), followed by DNA sequencing. The most targeted gene regions were cytb (cytochrome b) and COI (cytochrome c oxidase 1). Tuna was the most targeted commercial fish species. A case study of published tuna assays (n = 19) targeting the cytb region found that most assays were not species-specific through in silico testing. This was conducted by examining the primer mismatch for each assay using multiple sequence alignment. Therefore, there is need for more standardized DNA-based assay reporting in the literature to ensure specificity, reproducibility, and reliability of results. Factors, such as cost, sensitivity, quality of the DNA, and species, should be considered when designing assays.

Is the Compassion of Anesthesiologists Associated With Postoperative Pain and Patient Experience? A Prospective Cohort Study.

BACKGROUND: Patient perception of physician compassion may be associated with improved health outcomes, yet it is unclear whether it is associated with postoperative pain reduction or improved patient experience metrics in same-day surgery patients. We hypothesized that higher anesthesiologist compassion during the preanesthesia interview, rated by patients, is associated with lower postoperative pain via the anxiety pathway in same-day surgery patients. We also performed exploratory correlation analysis to assess whether compassion was associated with less opioid consumption and improved patient experience in same-day surgery patients. METHODS: We conducted a single-center, prospective, observational cohort study in American Society of Anesthesiologists (ASA) physical status I to III patients scheduled to undergo same-day surgery with anesthesia. Compassion was scored using a validated 5-item tool. State anxiety (SA) and trait anxiety (TA) were measured using the State-Trait Anxiety Inventory. Pain scores were obtained using a 0 to 10 Likert scale. Daily opioid use was recorded. Patient experience was assessed using the Consumer Assessment of Healthcare Providers and Systems Outpatient and Ambulatory Surgery Survey (OAS CAHPS) and the Surgical Care CAHPS. Mediation analysis was used to assess the association between compassion and pain scores via the anxiety pathway. Spearman correlation was performed to test for association between the compassion score and the secondary outcomes. RESULTS: A total of 147 subjects completed the study with a median age of 50 years and 81% female. Fifty percent underwent breast surgery, 35% abdominal surgery, and the rest underwent gynecological and urological surgeries. The median (Q1-Q3) postoperative pain scores on postoperative days 0 and 3 days later were 4 (1.5-6) and 3 (1-5), respectively.Mediation analysis results showed a same-day anxiety-mediated effect (95% confidence interval [CI]) of compassion on pain of -0.08 (-0.13 to -0.02), attributing to 9% of the total effect. On postoperative day 0, an increase in compassion was associated with a significant average drop in pain of between 0.02 and 0.13. In addition, higher compassion was correlated with better patient experience metrics (ρ= -0.53 [95% CI, -0.64 to -0.39]). CONCLUSIONS: The study results suggest that an anxiety-mediated pathway exists through which compassionate care may help improve the patient's perception of postoperative pain on the day of surgery (before discharge from the hospital). Higher compassion was also associated with better patient experience metrics.

Minimal Impact on the Resistome of Children in Botswana After Azithromycin Treatment for Acute Severe Diarrheal Disease.

BACKGROUND: Macrolide antibiotics, including azithromycin, can reduce under 5 years of age mortality rates and treat various infections in children in sub-Saharan Africa. These exposures, however, can select for antibiotic-resistant bacteria in the gut microbiota. METHODS: Our previous randomized controlled trial (RCT) of a rapid-test-and-treat strategy for severe acute diarrheal disease in children in Botswana included an intervention (3-day azithromycin dose) group and a control group that received supportive treatment. In this prospective matched cohort study using stools collected at baseline and 60 days after treatment from RCT participants, the collection of antibiotic resistance genes or resistome was compared between groups. RESULTS: Certain macrolide resistance genes increased in prevalence by 13%-55% at 60 days, without differences in gene presence between the intervention and control groups. These genes were linked to tetracycline resistance genes and mobile genetic elements. CONCLUSIONS: Azithromycin treatment for bacterial diarrhea for young children in Botswana resulted in similar effects on the gut resistome as the supportive treatment and did not provide additional selective pressure for macrolide resistance gene maintenance. The gut microbiota of these children contains diverse macrolide resistance genes that may be transferred within the gut upon repeated exposures to azithromycin or coselected by other antibiotics.

Efficacy of Ustekinumab and Vedolizumab Among Postoperative Crohn's Disease Patients as Postoperative Prophylaxis and Rescue Therapy: Real-world Data.

BACKGROUND: Almost half of patients with Crohn's disease (CD) require bowel surgeries in their lifetime. Due to the high risk of postoperative disease recurrence and high rate of previous antitumor necrosis factor (anti-TNF) failure, often alternative therapy options such as ustekinumab (UST) and vedolizumab (VDZ) are used. We aimed to evaluate the efficacy of UST and VDZ among postoperative CD patients as postoperative prophylaxis and rescue therapy. METHODS: Consented CD patients who underwent initial ileocecal resection and were treated with UST and VDZ were included in this study. Demographics, clinical characteristics, health care utilization, endoscopy scores, and surgery outcomes were collected. Postoperative early CD recurrence was defined as a Rutgeerts endoscopic score ≥i2 within the first 2 years. The rescue therapy group was defined as patients who received either UST or VDZ after having Rutgeerts endoscopic score ≥i2 postoperatively. RESULTS: During 2009 to 2019, 98 CD patients were treated with UST or VDZ postoperatively. Postoperative early recurrence rates were 5% (n = 1 out of 20) and 6% (1 out of 15) for the UST and VDZ groups, respectively. Two patients from the UST group and 1 patient from the VDZ group required bowel surgery during follow-up with median drug exposure of 51 (95% confidence interval [CI], 29-61) and 30 (95% CI, 14-63) months, respectively; 55% and 69% of patients had at least 1 point of improvement on postoperative endoscopic Rutgeerts score, respectively, for UST and VDZ. Only 3 out of 40 and 1 out of 23 patients required bowel surgery during follow-up while receiving UST and VDZ as rescue therapy. CONCLUSIONS: Both UST and VDZ were effective as postoperative therapies either as prophylaxis or rescue therapy.

This retrospective 11-year data examines the efficacy of ustekinumab and vedolizumab among postoperative Crohn's disease patients. When utilizing postoperative Rutgeerts score, this study confirms that both ustekinumab and vedolizumab were effective as postoperative therapies either as prophylaxis or rescue therapy.

Radar for Europa Assessment and Sounding: Ocean to Near-Surface (REASON).

The Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON) is a dual-frequency ice-penetrating radar (9 and 60 MHz) onboard the Europa Clipper mission. REASON is designed to probe Europa from exosphere to subsurface ocean, contributing the third dimension to observations of this enigmatic world. The hypotheses REASON will test are that (1) the ice shell of Europa hosts liquid water, (2) the ice shell overlies an ocean and is subject to tidal flexing, and (3) the exosphere, near-surface, ice shell, and ocean participate in material exchange essential to the habitability of this moon. REASON will investigate processes governing this material exchange by characterizing the distribution of putative non-ice material (e.g., brines, salts) in the subsurface, searching for an ice-ocean interface, characterizing the ice shell's global structure, and constraining the amplitude of Europa's radial tidal deformations. REASON will accomplish these science objectives using a combination of radar measurement techniques including altimetry, reflectometry, sounding, interferometry, plasma characterization, and ranging. Building on a rich heritage from Earth, the moon, and Mars, REASON will be the first ice-penetrating radar to explore the outer solar system. Because these radars are untested for the icy worlds in the outer solar system, a novel approach to measurement quality assessment was developed to represent uncertainties in key properties of Europa that affect REASON performance and ensure robustness across a range of plausible parameters suggested for the icy moon. REASON will shed light on a never-before-seen dimension of Europa and - in concert with other instruments on Europa Clipper - help to investigate whether Europa is a habitable world.

Growing pains with kratom: experiences discussed in subreddits contrast with satisfaction expressed in surveys.

Background: "Kratom" refers to an array of bioactive products derived from Mitragyna speciosa, a tree indigenous to Southeast Asia. Most kratom consumers report analgesic and stimulatory effects, and common reasons for use are to address mental and physical health needs, manage pain, and to reduce use of other substances. Natural-history studies and survey studies suggest that many kratom consumers perceive benefits from those uses, but such studies are unlikely to capture the full range of kratom-use experiences. Methods: We collected text data from Reddit posts from 2020-2022 to qualitatively examine conceptualizations, motivations, effects, and consequences associated with kratom use among people posting to social media. Reddit posts mentioning kratom were studied using template thematic analysis, which included collecting descriptions of kratom product types and use practices. Network analyses of coded themes was performed to examine independent relationships among themes, and between themes and product types. Results: Codes were applied to 329 of the 370 posts that comprised the final sample; 134 posts contained kratom product descriptions. As Reddit accounts were functionally anonymous, demographic estimates were untenable. Themes included kratom physical dependence (tolerance, withdrawal, or use to avoid withdrawal), perceived addiction (net detrimental effects on functioning), and quitting. Extract products were positively associated with reports of perceived addiction, dependence, and experiences of quitting kratom. Many used kratom for energy and self-treatment of pain, fatigue, and problems associated with opioid and alcohol; they perceived these uses as effective. Consumers expressed frustrations about product inconsistencies and lack of product information. Conclusion: As in previous studies, kratom was deemed helpful for some and a hindrance to others, but we also found evidence of notable negative experiences with kratom products that have not been well documented in surveys. Daily kratom use may produce mild-moderate physical dependence, with greater severity being possibly more common with concentrated extracts; however, there are currently no human laboratory studies of concentrated kratom extracts. Such studies, and detailed kratom product information, are needed to help inform consumer decision-making.

Pressure Injuries and Skin Failure.

Pressure injuries are a common chronic wound in the older adult. Care of pressure injuries is an interprofessional effort and involves physicians, nurses, registered dieticians, rehabilitation therapists, and surgical subspecialties. Numerous treatment modalities exist but have varying evidence to substantiate their efficacy. All primary and other care providers, particularly geriatricians, need to be aware of current evidence-based prevention and treatment standards. When healing is not expected, palliative care should be considered to avoid futile procedures and preserve dignity and quality of life.

Infectious Aspects of Chronic Wounds.

The treatment, maintenance, and suppression of infection in chronic wounds remain a challenge to all practitioners. From an infectious disease standpoint, knowing when a chronic wound has progressed from colonized to infected, when to use systemic antimicrobial therapy and when and how to culture such wounds can be daunting. With few standardized clinical guidelines for infections in chronic wounds, caring for them is an art form. However, there have been notable advances in the diagnosis, treatment, and management of infected wounds. This article will discuss the pathophysiology of infection in older adults, including specific infections such as cutaneous candidiasis, necrotizing soft tissue infection, osteomyelitis, and infections involving hardware.

Mobile App-Based Mindfulness Intervention for Addressing Psychological Distress Among Survivors of Hospitalization for COVID-19 Infection.

BACKGROUND: Psychological distress symptoms are present and persistent among many patients who survive a critical illness like COVID-19. RESEARCH QUESTION: Could a self-directed mobile app-delivered mindfulness intervention be feasibly and rapidly implemented within a clinical trials network to reduce distress symptoms? STUDY DESIGN AND METHODS: A randomized clinical trial was conducted between January 2021 and May 2022 at 29 US sites and included survivors of hospitalization due to COVID-19-related illness with elevated symptoms of depression at discharge. Participants were randomized to intervention or usual care control. The intervention consisted of four themed weeks of daily audio, video, and text content. All study procedures were virtual. The primary outcome was depression symptoms assessed with the Patient Health Questionnaire 9 at 3 months. Secondary outcomes included anxiety (Generalized Anxiety Disorder 7-item scale), quality of life (EQ-5D), and adherence. We used general linear models to estimate treatment arm differences in outcomes over time. RESULTS: Among 56 randomized participants (mean age ± SD, 51.0 ± 13.2 years; 38 female [67.9%]; 14 Black participants [25%]), 45 (intervention: n = 23 [79%]; control: n = 22 [81%]) were retained at 6 months. There was no difference in mean improvement between intervention and control participants at 3 months in Patient Health Questionnaire 9 (-0.5 vs 0.1), Generalized Anxiety Disorder 7-item scale (-0.3 vs 0.1), or EQ-5D (-0.03 vs 0.02) scores, respectively; 6-month results were similar. Only 15 participants (51.7%) initiated the intervention, whereas the mean number ± SD of the 56 prescribed intervention activities completed was 12.0 ± 15.2. Regulatory approvals delayed trial initiation by nearly a year. INTERPRETATION: Among survivors of COVID-19 hospitalization with elevated psychological distress symptoms, a self-directed mobile app-based mindfulness intervention had poor adherence. Future psychological distress interventions mobilized at broad scale should focus efforts on patient engagement and regulatory simplification to enhance success.

Association of cancer treatment with excess heart age among five-year young breast cancer survivors.

PURPOSE: Data evaluating cardiovascular disease (CVD) risk by cancer treatment among young women (≤ 40 years) with breast cancer are limited. METHODS: Among 372 five-year breast cancer survivors aged 30-40 years from the Young Women's Breast Cancer Study, we assessed the association of cancer treatments (anthracyclines, trastuzumab, radiation/laterality, endocrine therapy) and excess heart age (difference between predicted 10-year CVD risk as assessed by adapted Framingham Risk Score and chronological age), prevalent elevated excess heart age (≥ 2 years), and worsening excess heart age (change of ≥ 2 excess heart age years) at breast cancer diagnosis and two- and five-year follow-up using multivariable linear and logistic regressions. RESULTS: Most women had stage I or II (79%), ER + (71%), or PR + (65%) breast cancer. At diagnosis, women had little excess heart age by treatment receipt (range of means = -0.52,0.91 years). Left-sided radiation (ß = 2.49,SE = 0.96,p = 0.01) was associated with higher excess heart age at five-year follow-up. For prevalent elevated excess heart age (two-year = 26%;five-year = 27%), women treated with right-sided radiation had increased risk at two-years (OR = 2.17,95%CI = 1.12-4.19), yet at five-years, associations were observed after any radiation (OR = 1.92,95%CI = 1.09-3.41), especially after left-sided (OR = 2.13,95%CI = 1.09-3.41) radiation. No associations were observed between systemic treatments and prevalent elevated excess heart age or any treatments with worsening excess heart age. CONCLUSIONS: Among young breast cancer survivors, radiation, but not other cancer treatments, was associated with elevated excess heart age. IMPLICATIONS FOR CANCER SURVIVORS: CVD risk tools that incorporate cancer treatment, such as radiation, are needed to identify high risk young breast cancer survivors given the long survivorship and long latency of cardiovascular disease.

Multilevel Interventions and Dental Attendance in Pediatric Primary Care: A Cluster Randomized Clinical Trial.

Importance: Untreated tooth decay is disproportionately present among low-income young children. While American Academy of Pediatrics (AAP) guidelines require pediatric clinicians to implement oral health care, the effectiveness of these oral health interventions has been inconclusive. Objective: To test the effectiveness of multilevel interventions in increasing dental attendance and reducing untreated decay among young children attending well-child visits (WCVs). Design, Setting, and Participants: The Pediatric Providers Against Cavities in Children's Teeth study is a cluster randomized clinical trial that was conducted at 18 pediatric primary care practices in northeast Ohio. The trial data were collected between November 2017 and July 2022, with data analyses conducted from August 2022 to March 2023. Eligible participants included Medicaid-enrolled preschoolers aged 3 to 6 years attending WCVs at participating practices who were enrolled at baseline (WCV 1) and followed-up for 2 consecutive examinations (WCV 2 and WCV 3). Interventions: Clinicians in the intervention group received both the practice-level (electronic medical record changes to document oral health) and clinician-level (common-sense model of self-regulation theory-based oral health education and skills training) interventions. Control group clinicians received AAP-based standard oral health education alone. Main Outcomes and Measures: Dental attendance was determined through clinical dental examinations conducted by hygienists utilizing International Caries Detection and Assessment System criteria and also from Medicaid claims data. Untreated decay was determined through clinical examinations. A generalized estimating equations (GEE) approach was used for both clinical examinations and Medicaid claims data. Results: Eighteen practices were randomized to either intervention or control. Participants included 63 clinicians (mean [SD] age, 47.0 [11.3] years; 48 female [76.2%] and 15 male [23.8%]; 28 in the intervention group [44.4%]; 35 in the control group [55.6%]) and 1023 parent-child dyads (mean [SD] child age, 56.1 [14.0] months; 555 male children [54.4%] and 466 female children [45.6%]; 517 in the intervention group [50.5%]; 506 in the control group [49.5%]). Dental attendance from clinical examinations was significantly higher in the intervention group (170 children [52.0%]) vs control group (150 children [43.1%]) with a difference of 8.9% (95% CI, 1.4% to 16.4%; P = .02). The GEE model using clinical examinations showed a significant increase in dental attendance in the intervention group vs control group (adjusted odds ratio, 1.34; 95% CI, 1.07 to 1.69). From Medicaid claims, the control group had significantly higher dental attendance than the intervention group at 2 years (332 children [79.6%] vs 330 children [73.7%]; P = .04) but not at 3 years. A clinically but not statistically significant reduction in mean number of untreated decay was found in the intervention group compared with controls (B = -0.27; 95% CI, -0.56 to 0.02). Conclusions and Relevance: In this cluster randomized clinical trial, children in the intervention group had better dental outcomes as was evidenced by increased dental attendance and lower untreated decay. These findings suggest that intervention group clinicians comprehensively integrated oral health services into WCVs. Trial Registration: ClinicalTrials.gov Identifier: NCT03385629.

The Surgical Infection Society Guidelines on the Management of Intra-Abdominal Infection: 2024 Update.

Background: The Surgical Infection Society (SIS) published evidence-based guidelines for the management of intra-abdominal infection (IAI) in 1992, 2002, 2010, and 2017. Here, we present the most recent guideline update based on a systematic review of current literature. Methods: The writing group, including current and former members of the SIS Therapeutics and Guidelines Committee and other individuals with content or guideline expertise within the SIS, working with a professional librarian, performed a systematic review using PubMed/Medline, the Cochrane Library, Embase, and Web of Science from 2016 until February 2024. Keyword descriptors combined "surgical site infections" or "intra-abdominal infections" in adults limited to randomized controlled trials, systematic reviews, and meta-analyses. Additional relevant publications not in the initial search but identified during literature review were included. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) system was utilized to evaluate the evidence. The strength of each recommendation was rated strong (1) or weak (2). The quality of the evidence was rated high (A), moderate (B), or weak (C). The guideline contains new recommendations and updates to recommendations from previous IAI guideline versions. Final recommendations were developed by an iterative process. All writing group members voted to accept or reject each recommendation. Results: This updated evidence-based guideline contains recommendations from the SIS for the treatment of adult patients with IAI. Evidence-based recommendations were developed for antimicrobial agent selection, timing, route of administration, duration, and de-escalation; timing of source control; treatment of specific pathogens; treatment of specific intra-abdominal disease processes; and implementation of hospital-based antimicrobial agent stewardship programs. Summary: This document contains the most up-to-date recommendations from the SIS on the prevention and management of IAI in adult patients.

Current patterns of care and outcomes for dermatofibrosarcoma protuberans: An international multi-institutional collaborative.

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a cutaneous sarcoma with an infiltrative growth pattern that makes it challenging to clear margins. High quality data regarding DFSP natural history, management, and outcomes are limited. METHODS: Data were retrospectively collected for adult DFSP patients who underwent resection at 10 institutions in eight countries. Demographics, tumor characteristics, treatment strategies, and outcomes were analyzed. RESULTS: Analysis included 347 patients consisting of young (median, 42 years), White (76.2%), males (54.2%) with truncal lesions (57.3%). The majority (76.8%) were symptomatic at presentation. Preoperative imaging was used in 55.9% of cases. Diagnosis was established with excisional biopsy in 50.9% versus incisional biopsy in 25.0% of cases. Despite planned margins of >1.0 cm in 67.4% of cases, only 69.0% of patients achieved R0 resection. Twenty-two percent of patients underwent at least one re-excision. R0 resection was achieved at a second procedure in 80.2% and a third procedure in 86.2%. Ultimately, R0 resection was feasible in 89.5% of all patients. Fibrosarcomatous transformation (FST) was observed in 12.6%. In total, 6.6% (N = 23) recurred (17 local, six distant). Of the six distant recurrences, 50.0% had FST. With a median follow-up of 47.0 months, disease-specific survival rate was 98.8%. In multivariable analysis, R0 margins at index resection were associated with wider circumferential margins and non-FST histology. CONCLUSIONS: In this international, multicenter collaborative, DFSP practice patterns were heterogeneous but achieved favorable recurrence rates and survival. Multiple excisions to clear margins remain commonplace and can inform future efforts to optimize margin selection.

Anxiety symptoms predict head and neck cancer survival: Exploring mediation by systemic inflammation and tumor response to treatment.

BACKGROUND: Head and neck cancers (HNC) are associated with high rates of anxiety. Anxiety has been linked to biological pathways implicated in cancer progression, though little is known about its effects on overall survival. We hypothesized that higher pretreatment anxiety levels in patients with HNC would predict poorer 2-year overall survival and expected this relationship to be mediated by both systemic inflammation and tumor response to treatment. METHODS: Patients (N = 394) reported anxiety symptomatology via the GAD-7 at treatment planning. Pre-treatment hematology workup provided an index of systemic inflammation (SII; N = 292). Clinical data review yielded tumor response and overall survival. Logistic and multiple regressions and Cox proportional hazard models tested hypothesized relationships. RESULTS: Higher pretreatment anxiety levels were significantly associated with poorer 2-year survival (hazard ratio [HR], 1.039; 95% confidence interval [CI], 1.014-1.066, p = 0.002). The association between anxiety and SII was not significant, though anxiety was associated with poorer tumor response (odds ratio [OR], 1.033; 95% CI, 1.001-1.066, p = 0.043). Tumor response fully mediated the relationship between anxiety symptoms and 2-year survival (HR, 9.290, 95% CI, 6.152-14.031, p < 0.001). CONCLUSIONS: Anxiety was associated with overall survival. Tumor response, but not systemic inflammation, emerged as a potential biological pathway mediating this effect. Screening for anxiety may be beneficial to help prospectively address these concerns and ameliorate potentially detrimental impact on clinically meaningful cancer outcomes.

Does preoperative symptom duration affect outcomes following per oral endoscopic myotomy (POEM)?

BACKGROUND: Per oral endoscopic myotomy (POEM) is a safe therapy for the treatment of achalasia. Long-term effects of untreated achalasia include worsening dysmotility and disruptions in esophageal anatomy, i.e., tortuosity and dilation. We hypothesize that long-standing achalasia prior to intervention will have worse outcomes following POEM than in patients with symptoms for shorter duration. METHODS: We retrospectively analyzed achalasia patients who underwent POEM at our institution from 2011 to 2023, categorizing them into symptom duration cohorts (< 1 year, 1-3 years, 4-10 years, > 10 years). Inclusion criteria comprised patients with documented achalasia diagnosis who received POEM treatment at our facility. Exclusion criteria encompassed individuals lacking data pertaining to achalasia diagnosis, the time frame before intervention, or those missing pre and postoperative Eckardt scores. POEM failure was defined as symptom recurrence, necessity for repeat intervention, or high postoperative Eckardt score. We compared demographic, preoperative, and postoperative outcomes across these cohorts, and employed multivariable logistic regression to explore the link between symptom duration and POEM response. RESULTS: During the study period, in our increased cohort 234 patients met inclusion criteria. 75 patients had symptoms for < 1 year, 78 patients had symptoms from 1 to 3 years, 47 patients had symptoms from 4 to 10 years, and 34 patients had symptoms > 10 years. Patient demographics such as age, sex, BMI, Charleson-Deyo-Comorbidity-Index, and diabetes did not differ amongst cohorts. High-resolution manometry data, including achalasia type, Median IRP, LES residual pressure, and Basal LES pressure did not differ between groups. Preoperative Eckardt scores ranged from 4 to 5 across groups (p 0.24). Patients endorsed an average of three total preoperative symptoms across groups (p 0.13). Patients with symptoms greater than 4 years had significantly more endoscopic interventions prior to POEM (37% vs, 68% p .001). There was no significant difference in post-procedure mean Eckardt scores between cohorts. All cohorts experienced the same number of post-POEM symptoms. Post-POEM manometric measurements remained consistent across cohorts. Similarly, there were no significant differences in terms of symptom recurrence, requirement for repeat interventions, or repeat POEM among the cohorts. Multivariable logistic regression analysis determined achalasia symptoms greater than a decade did not result in increased odds of having a higher postoperative Eckardt score, worse dysphagia, regurgitation, or weight loss. CONCLUSIONS: In this increased cohort, this data once again suggests that longer symptom duration is not associated with increased rates of POEM failure.
